SHOCKING-IXIAOHINE.

Specification of Letters Patent.

Patented May 15, 1917.,

Application filed November 17, 1913. Serial No. 801,525.

i'b all whom it may concern:

Be it known that I, CLEMMA R. RANEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shocking-llIachines, of which the following is a full, clear, and exact specification.

My invention relates to shocking machines.

In shockers of the type employing a swinging sheaf delivery member, wherein the sheaf delivery member is pivoted on the shocker frame and swings back and forth from sheaf receiving position beneath the binder deck to sheaf delivery position over the shocker cradle, it has been found that the sheaf delivery member, after it passes over its center in its backward movement, is accelerated or speeded up by the pull of gravity to such a degree that it has a tendency to rebound when it strikes its support beneath the binder deck, with the result of seriously interfering with the operation of the shocker due to the displacement of the fork when the next sheaf is discharged. Further, there has been an undue amount of wear and tear upon the machine due to the continued hammering of the sheaf delivery member against its support.

My invention has for its object to eliminate this objectionable rebounding or hammerina of the shocker sheaf delivery member as the latter returns to its sheaf receiving position after the delivery of a sheaf. I attain this object by providing retarding means operatively connected to the sheaf delivery member and a source of power operating at a constant speed, whereby, as the sheaf delivery member, in passing over its.

center, is attracted by the pull of gravity, this member is automatically connected to mechanism moving at a slower, constant speed, thus eliminating any tendency to increase of speed due to the pull of gravity.

In the accompanying drawings I have shown one form which my invention may assume in practice. It is to be understood, however, that the form shown herein. for purposes of illustration may be modified without departing from the spirit of the invention.

In these drawings:

Figure 1 is a side elevation of the shocker equipped with my improvement;

Fig. 2 is a top plan view of a portion of the operating mechanism;

Fig. 3 is a detail view of the clutch mechanism partially in transverse section;

Fig. f is a longitudinal section of the clutch mechanism.

The shocker illustrated herein is of the type described and claimed in my copendmg application, Serial No. 573,106, filed July 21, 1910. This shocker comprises a main frame 1, having a transversely disposed operating shaft 2 journaled thereon, upon which is fixed a sheaf delivery memher 3, shown in the form of a fork, movable hack and forth in a vertical plane with the shaft 2 from the dotted line or sheaf receiving position shown in Fig. 1, wherein it rests on a support -l carried on the binder frame (not shown) to the full line or sheaf delivery position shown in that figure; the shaft 2 being carried on the upper part of the frame and operatively connected to a suitable, continuously operating source of power disposed beneath the same, such as a shaft 5, through a longitudinally disposed chain 6, a transverse shaft 7 a sprocket 8 carried on said shaft, and a resilient pitman connection 9 operatively connected between the shafts 2 and 7, and being controlled by means of a longitudinally disposed rocking trip arm 10, operated by the sheaves as they are discharged from the binder deck and having a finger 11 engaging the clutch finger of a clutch 12 carried on the shaft 7 and adapted to be operatively connected to the constantly rotating chain and sprocket connection to throw the fork 3 into operation when the trip 10 is actuated by a sheaf engaging therewith.

Associated with this sheaf delivery 1nem her or fork 3 are means for cushioning the fork 3 when it reaches its dotted line or sheaf delivery position over the shocker cradle, and at the same timeimparting a quick return movement to the latter to disengage the same from the delivered sheaf. These means comprise a laterally extending arm 13 fixed on the shaft 2 at 14 and engaging a second arm 15 rotatably mounted beside it on the shaft 2 and adapted to abut against a coiled spring 16 to place the same under tension as the fork 3 moves to sheaf delivering position, thus cushioning the blow of the fork and storing power in the spring, which, after the fork has completed its travel, acts to start the same backward with a quick movement, separating the same from the delivered sheaf. As shown, the spring 16 is coiled around an arcuate rod 17, fixed to the end of the movable arm 15, and eX- tends between the arm 15 and a fixed abutment or b 'acket 18, carried on the frame 1, through which moves the free end of the rod 17 within the limits prescribed by the spring 16 and a pin 19.

Cooperating with the fork 3, and cushioning means therefor just described, is my improved retarding mechanism for the fork. This mechanism, as shown in Figs. 3 and 4, includes a sprocket 20 continuously driven by the chain 6 at the same or greater speed than the fork in the first stages of its rearward movement. This sprocket is rotatably mounted in the plane of the sprocket 8 and above the same on a sleeve 21 fixed on the shaft 2 and, as shown, is provided with a serrated or toothed inner surface or periphery 2:2 adapted to be engaged by a pawl 23 pivotally mounted on a pin 24 carried on the arm 13 and rotatable therewith; a spring 25 being provided therefor which encircles the pin 2% and is operatively connected at its ends to both the pawl 23 and the arm 13 in such a manner that it normally holds the pawl in engagement with the teeth on the inner periphery of the sprocket 20 and locks the fork 3 to this constantly rotating sprocket when, as the arm 13 is rotated in a clockwise direction, the speed of movement of the fork 3 tends to exceed the speed of the sprocket.

The operation of the construction shown is as follows: Assuming that the fork 3 is in the full line position shown in Fig. 1, upon the return of the same to its dotted line or sheaf receiving position, due to the use of the yielding or resilient pitman drive, there would obviously be a tendency for the fork to accelerate or speed up after it has passed its vertical position, with the result that the tined end of the fork 3 would strike its support 4: with a heavy blow, causing the rebound of the fork. By the provision of my improved retarding mechanism it is to be noted that as the fork moves past its vertical position, the pawl 23 remains in engagement with the serrated inner surface of the sprocket 20 in such a manner as to connect the fork with the constantly rotating power connection 5 through the chain 6, and thus remove any tendency for the fork to speed up, the fork, instead, being lowered from its vertical to its prostrate or sheaf receiving position at a constant speed. Obviously,

when the next sheaf is ejected from the binder and strikes the trip 10, the fork 3 will again be operated through the pitman connection 9 upon actuation of the clutch 12 by the trip, the fork being freely movable backward about its pivot to sheaf delivery position as the pawl 23 then runs freely over the serrated inner surface of the sprocket 20 in the reverse direction from that just described.

lVhile I have in this application described one specific form of my invention with a view to disclosing the same in the manner prescribed by the statutes, it is, of course, to be understood that the form shown herein may be modified without departing from the spirit of my invention.
